Breathing k-Gap Events and Instability on Instability in Nonlinear Photonic Time Crystals
Liang Zhang, Chenhao Pan, Yiming Pan
Photonic time crystals (PTCs) host momentum bandgaps, or k gaps, that enable parametric amplification and lasing of seeded fields. In nonlinear PTCs, Kerr saturation dynamically su…
Quantization and Biphoton Statistics of k-Gap Solitons in Nonlinear Photonic Time Crystals
Liang Zhang, Chenhao Pan, Yiming Pan
Nonlinear photonic time crystals (PTCs) can support solitons inside momentum k gaps, where the amplification of k gap modes is saturated by Kerr nonlinearity, forming spatially hom…
Quantum echo-enabled high harmonic generation using ultrafast electrons
Yangfan He, Chenhao Pan, Bin Zhang +1
Controlling and generating ultrafast free-electron wavepackets via laser is pivotal for photon-induced near-field electron microscopes (PINEM) and also for developing compact, cohe…
Programming Coherent and Quantum Light with a Free-Electron Wavepacket
Songyu Zhu, Yushan Zeng, Chenhao Pan +3
The pursuit of compact, programmable light sources with high coherence and spectral purity hinges on establishing a precise set of phase relationships in light-matter interactions.…
